A talent agent named Johnny Jackson (Laurence Harvey) tries to resurrect his flagging career when he stumbles upon a talented young rock 'n' roll musician, Bert Rudge (Cliff Richard). Although Rudge protests and says he doesn't want to be a star, Jackson transforms the youth into a teen idol, renaming him Bongo Herbert. Pretty soon, Bongo Herbert is making it big, with a single hitting the charts and Jackson pulling the strings. But, as the two find out, success is fleeting.
